The invention discloses a micro-propeller based on phase change. The micro-propeller based on phase change comprises a propeller body and nozzles. Each of the nozzles comprises a glass nanotube, a gold nanorod, liquid fluorocarbon, PLGA nanoparticles and a laser generator. The glass nanotube is of a cylindrical structure, and a tip outlet is formed in the tail portion; the gold nanorod, liquid fluorocarbon and PLGA nanoparticles are arranged in the glass nanotube, and the gold nanorod is arranged on an axis portion of the glass nanotube; the laser generator is arranged in the axis position out of the glass nanotube, and the laser generator is connected to the bottom of the glass nanotube. By controlling the diameter of the outlet of the glass micro and nanotube, the jet flow is controlled, and meanwhile, in a liquid condition, as a result of surface tension, the liquid fluorocarbon is kept not leaked; the vaporizing rate of the liquid fluorocarbon is controlled by controlling the power of the laser generator so as to control the propelling speed of the propeller, so that a mini satellite operates at different rates; the nozzles are mounted in array on the satellite, so that a huger thrust can be provided and different directions of the satellite can be controlled.
